(a) skin.
(b) hair.
(c) bone.
(d) fluid.
Best Answer

Air is a mixture of various gases and many minute unwanted particles present in it. When any such particle is inhaled, it gets trapped in the hair present in our nasal cavity. Sometimes, instead of getting trapped by hair, they reach the lining of nasal cavity and irritation occurs.
